I don't think you remember correctly, given how Iwobi and Silva were with us for about 10 (mostly dreadful) games - Lampard faced a bit more flak for it* I think and Iwobi himself had a mini-feud with Ancelotti about his position randomly, but he was mostly dreadful for us.
Also the loudest criticism for this was and always will be
@TheBigIguana I think, so you more or less fell for that discussion being brought up on here every day or two. Outside of Big Iggo, the biggest critic of "where Iwobi is being played" was Iwobi.
* EDIT: In that Lampard team Iwobi was genuinely better through the middle imho, but it honestly means nothing as it was another dreadful period.
